An RE SXX 12" is on it's way to my house now, and I'm trying to design a box for it now. I'm using WinISD now, and trying to get a good box designed before I start cutting wood. RE Audio recommends 2 cubic feet at 35Hz, but I want to tune a bit lower, around 31 or 32Hz. So because of the size of my trunk, I'm pretty set on the following for dimensions:
15"H x 19"W x 15"L (length being depth in this case)
These are all inside dimensions.
Where I need help is the port. Using WinISD, the best I have found is this:
2"W x 15"H x 28"D
This gives me a tuning frequency at or just a bit below 31Hz, and a Vent Mach of .07.
This is my first quality build, so I'm looking to get it right the first time, as I don't want to be building another box for this driver because I could have done a better job the first time. Any/all help is appreciated.
